Application. filed November To all whom t may concern:

Be. it known that l, Gnonon H. Lmrrrnrr, a citizen of the United States,residing at Aurora, in the county of Kane, State of illinois, haveinvented certain new and useful improvements in Liquid-Fuel Burners, ofwhich the following is a specification.

rlllhe object of my invention is to provide a highly eflicient andtherefore economical burner for liquid fuel such as kerosene, forexample, that is especially adapted for use in the lire boxes of cookingand heating stoves, and with this object my invention consists in theburner having the characteristics of construction defined by or includedwithin the scope of the appended claims.

In the accompanying` drawing:

Fig. 1 is a vertical section of a burner embodying my invention;

Fig. 2 is a front elevation thereof;

Fig. 3 is a top plan view.

Describing in detail the embodiment of my invention shown in thedrawings, such embodiment has a base, 10, of sheet steel that is ofsubstantially Ushape, below the top and between the legs of whichextends the oil feed pipe, 11, provided with a controlling valve, 12.,and to the top of which base is bolted a platform or bracket, 13, whichprojects beyond one edge of said base and has a vertical hole, 1li, forthe passage of the. vertical pipe portion, 15, of the burner, the lowerend of said pipe portion beneath said platform being screwed to anelbow, 16, which is connected with the feed pipe. rlllhe platform isbi'l'urcated so as to provide two diverging lugs, 17, and upon thelatter is mounted a horizontal baille plate, 1S, that is substantiallyof disk form and which is fixed in position by two bolts, 19, which passdown through'holes in the baille plate and through holes in the lugs andthrough holes in the horizontal portion of the base, 10, thus the samebolts serving to unite base, platform and baflie plate.

The pipe or tube, 15, at a substantial distance above the bafile plateis bent into a partial coil that comprises an upper hori- Zontalportion, 20, and a lower horizontal portion, 21, the end 0f the latterbeing closed and its underside having` a fuel outlet, 22, situatedsubstantially centrally above the baille plate so that fuel in a gasSpecification of Letters Patent.

forni is discharged therefrom and delivered to the top of the baffleplate where combustion takes place and a flame is produced that spreadsover the top surface of the baffle plate and extends upward into thefire boa: producing therein an intense heat. The top of the baille plateis preferably slightly dished as best shown in F ig. 1. rEhe pipe ortubing is preferably of steel and the fuel outlet therefrom. ispreferably provided in a brass plug, 23. The plug projects into the tubeand the outlet through the plug tapers from its inner end outward thusmak ing it impossible for the opening to become clogged loy the lodgmentof material therein.

The connection between the baffle plate supporting` platform and thevertical pipe portion, 15, is a slidable one so that by moving theplatform up or down upon suoli pipe portion the proper distance from the`gas outlet to the top ofthe baffle plate may be secured and therebythat relative position of outlet and baffle plate secured which isnecessary to give proper combustion and securey the highest efficiencyof the fuel. lhen the desired adjustment is made, the platform is linedto the pipe as by means of a set screw, 25, which passes through athreaded hole in thepipe encircling por tion of the platform and bearsagainst the side of the pipe.

l/Vhat l" claim is:

1. A liquid fuel burner comprising a horizontal baille plate, a platformon which the baffle plate is mounted, a base, means connecting base,baille plate, and platform, and a pipo having` a fuel outlet andsituated a spaced distance above said baille plate,i said pipe having avertical. portion upon which said platform is mounted for adjustmenttowards and from said outlet.

2. A liquid fuelV burner comprising a base, a baffle plate, a platformon which the baille plate is mounted, means vconnecting said base,baille plate and platform, a pipe passing vertically through an openingin said support, and a set screw for securing said support to said pipe,said pipe being doubled upon itself above the baille to provide hori-Zontal portions at different levels, the lower portion having a gasoutlet in its underside.

In testimony whereof l hereunto aliix my signature.

GEORGE H. LEFHET.
